Mosaddegh's political activities raised an ire during the reign of Reza Shah as well as his son Mohammad Reza Shah's. Reza Shah had imprisoned Mosaddegh in Birjand and then sent him to Ahmadabad near Karaj. Mosaddegh was kept under house arrest. Reza Shah was forced to abdicate in favour of his son in 1941 after Allied Powers invaded Iran. He was forced to leave the country, taken in a British ship to the Maurice Island, and then to South Africa, where he died.As a part of a general pardon that followed Mohammad Reza Shah's accession to the throne that year, some prisoners including Mosaddegh were set free. Mosaddegh kept on his activities for democracy and defending people's rights. He was elected as the first parliament representative from Tehran. After the military coup in 1953 he was sent to prison again. After 3 years he was sent to Ahmadabad and kept there in exile for the rest of his life until he died.
